WINDSHIELD ATTAGHIEENT.

T 0 all whom it may concern:

Be it known that we JOSEPH H. Vrrmnnns, JOHN HALLIDAY, and Josnrr-rPRESNER, all subjects of the King of Great Britain, and residents of thecity of Montreal, Province of Quebec, Dominion of Canada, have inventedcertain new and useful Improvements in Windshield Attachments; and we dohereby declare that the following is a full, clear, and exactdescription thereof.

Our invention relates particularly to attachments of the type disclosedin a pending application Serial No. 443,466 for shielding the eyes ofthe occupants of motor vehicles from the suns rays and for protect ingthe wind shield glass particularly the upper section of the latter fromrain, snow or sleet.

he object of the present invention is to provide an attachment of thisnature possessing increased efficiency and greater durability and whichcan be manufactured at a comparatively low cost.

To this end our invention consists of the construction, combination andparticular arrangement of the parts hereinafter described andillustrated and pointed out in the claims.

The accompanying drawing illustrates the preferred embodiment of ourinvention which consists of a tubular casing 2 having a longitudinalopening3 and closed ends 42 and 5. This casing contains an all-metalroller 6 which is j ournalled in the ends 1 and 5 respectively, theroller having wound there on a blind 7 which is adapted to be extendedoutwardly through the opening in the cue ing. Means for extending theblind comprises a pair of lever arms 8 and 9 one of which is pivotallymounted upon each end of the casing 2 with the front ends of the arms inoperative engagement with a reinforcement device 10 upon the front edgeof the blind and adapted to swing outwardly from a positionsubstantially parallel to the casing to a position oblique thereto thelat ter position being determined by the size of the blind.

This reinforcement device preferably con. sists of a sheet-metal memberbent to sub stantially U-form in cross-section to present a channel 12into which the said front end of each lever arm projects. The latter isof angular cross-section between its ends and is so disposed that oneflange is adapted to operate within the channel 12 such flange lyingwithin the channel substantially throughout its length when the blind isin the withdrawn position. The outer end of such flange is of increasedwidth and presents a curved bearing surface 13 the curve beingsufficiently wide to prevent undue wear on the reinforcement member 10.The opposite end of each arm is forked as at 1 1 to effect its pivotalconnection to the adjacent end of the casing and it is provided with atail 15 which is operatively connected to the corresponding tail on theother arm by springs 16 and 17 the springs imparting to the arms atendency to swing outwardly relatively to the casing for the purpose ofyieldingly maintaining the blind in extended position. This constructionand arrangement of parts also maintain the front ends of the arms inbearing relation with the reinforcement member 10 without the aid ofmeans for fastening the reinforcement member and arms together therebyproviding a more durable, cheaper and more eflicient construction thanis obtainable if additional means for securing each arm to thereinforcement "to be fitted within the ends of the tube and providedwith preferably three lugs or clips 21 which are sprung over the adacent end of the tube, the clips belng of su'ilicient depth to present ashallow socket 22 ateach end of the roller'into which a hub or boss 23projects,this boss being formed mtegrally with each of the casing ends 4and 5 respectively. The closure 19 rigidly carries a trunnion 24 whichis journalledin the adjacent boss. The'mount for the roller at itsopposite end is effected by a comparatively short shaft 25 disposedlongitudinally within the roller tube and having its inner end rotatablymounted in a block 26 rigidly secured within the tube. The outer end ofthe shaft projects through acentral opening 27 in the disc 20 and isflattened as at 28 and inserted into a slot in the ad acent boss on thecasing end, the shaft being thus held against rotation but permittingrotation of the-roller. A connection between the two is efiectcd througha helical spring'29 which encircles the shaft throughout its length andhas its inner end secured in a slot or opening'SO in such shaft itsopposite end 31 projecting through a hole 32in the disc 20.

As hereinbefore stated, the size of the blind determines the extent ofits projection, that is to say, it is extended untilcompletely unwoundfrom the roller. It is obvious, therefore, that the connection of theinner end of theblind to the roller must be such that such inner endwill not be subjected to undue wear" and tear when the fluid isextended. To provide such a connection which will also enable the blindto be read ily detached from the roller the tube 6 is provided with alongitudinal opening 33 extending throughout its length and the edgesthereof are bent back as at 34 and 35 for reinforcement purposes. Theblind is adapted to be projected through this opening and its inner endis sewn around a rod 36 located within the roller and extendingthroughout the length of the same and of a diameter larger than thewidth of the opening for prevent-in complete displacement from theroller. Each end of the rod is provided with an eye-36 and the blind isstretched thereon'and secured thereto at its ends by wire fasteningswhich are threaded through such eyes thereby preventing wrinkling inservice. In order to ensure uniform winding of the blind on the rollertended position.

acting a pawl preventing such rotation.

This may be employed at opposite ends of the roller if it'is desiredtohave a closure for such end detachable, one enfdhowever only need bedetachable to permit insertion of the rod 36 into the roller. It may befound desirable to employ blocks similar to the block 26 spacedthroughout the length of the tube 6 for the purpose of reinforcement.

The block 26" is cut away as at 41 to accommodate the rod 36. The outerend of the blind is secured to the reinforcement bar 10 the connectionbeing efl'ectedby carrying the" blind over the front edge of the bar andbeneath the same where it is secured in a relatively small tube 43formed by bending the adjacent edge of the bar to cylindrical form, theblind being secured in the tube by rod 44 which is sewn into theblindand its ends being secured to the ends of the blind ina similar mannerto rod 36. The

endwise the longitudinal opening 45 being provided to accommodate theblind.

In order to withdrawthe blinda wirecord 46 is secured to the undersideof the bar 10 is passed through a lock 47 mounted on the casing 2 to apoint in the vehicle withinreach of the driver whereby the latter by apull on the cord maywithdraw the blind when desired. The I lock 47 whichmaintains the blind in the'withdrawn position consists of a unitarymember 48 having a tapered opening 49 through which the cord passes.Positioned centrally of the mouth of the larger end of such opening is amovable jaw 50 actuated by a spring51. This jaw has concave faces 52 and53 and is adapted to engage an enlargement 54 on the cord. The cord maybe released trom'the position in which it is locked by the jaw by movingthe cord with its enlargement laterally until such enlargement clearsthe jaws. The springs 16 and 17 are of suflicient strength to overcomethe spring 29 so that the blind, unless held in'withdrawn position bythe cord 46, will normally assume its eX- The casing 2 is adapted to besecured to the motor vehicle in any preferred manner. In the accompanyindrawing a forked bracket 55 is mounte rod is adapted to be inserted intothe tube upon each end of the casing-2 and adjust i ably carries a pairof clamping jaws 56, the adjustment enabling the attachment to besecured to Windshields of varying width.

This adjustment is obtained by slidably mounting the head of a bolt 57which carries the jaws in the fork of the bracket.
